UNITED STATES WILLIAM JAMES BURTON, OF WINNIPEG, MANITOBA, CANADA.

WEEI) ERADICATOR.

Application led July 5,

The invention relates to improvements in weed eradicators and an object of the invention is to provide a device which will eitectively cut the soil, loosen and separate the weeds theret'rom and leave the weeds lying on the ground surface.

A further object ot the invention is to provide a device particularly adapted to eradicating sow-thistle, quack A grass and other such obnoxious growths.

A further object is toprovide a weed eradicator in the form of a shoe which can be attached to the present types ofstitf teeth cultivators, thereby permitting the 'farmer h vstill3 tooth cultivators, and in the present into use his cultivator with my attachment to eradicate weeds.

A further object is to construct the device in a simple, durable and inexpensive manner and so that it can be readily attached to or dismounted from the teeth of the cultivator.

With the above more important objects in view the invention consists essentially in the arrangement and construction ot parts hereinafter more particularly described, reference being had to the accompanying drawing, in which Fig. 1 is a vertical sectional view through a stiff tooth cultivator, parts being shown in side elevation and the cultivator being equipped with my invention.

Fig. 2 is a plan view ot my improved shoe.

Fig. 3 is an enlarged detailed vertical sectional view at 3 3 Fig. 2.

Fig. 4 is an enlarged detailed vertical sectional view at 4 4 Fig. 2.

Fig. 5 is an enlarged detailed vertical sectional vie-w at 5-5 Fig. 2.

In the drawing like characters of re'terence indicate corresponding parts in the several iigures.

In the present disclosure I have shown a stiff tooth cultivator of the ordinary type equipped with my invention, but in this connection I wish it to be distinctly understood that a separate machine can be builtand equipped with my shoes, as in so far as their work is concerned it is only necessary that they be held in working position in the ground.

The stiff tooth cultivator which is ot the usual form presents a substantially rectangular frame 1 which is supported by the customary ground wheels, one of which is shown at 2. To the forward end of the frame, pairs of rearwardly extending bars 3 are pivotally connected at l and the rear 1924. Serial No. 724,441.

,ends of the bars 3 carry shanks 5 which eX- tend downwardly towards the ground and are fitted with teeth 6. The frame carries a seat 7, adjoining which there is anadjusting lever 8 and the adjusting lever operates through suitable cranks 9 provided to apply pressure on therear ends of the bars 3, and in so doing hold the teeth into the ground.

A morev detailed description of the stift tooth cultivator is not herein given as such a machine is well known to those familiar with farming operations.v

Different types of teeth 6 are provided for stance I have shown the type of tooth known as the duck toot, such being in the form of a pointed or V-shaped inclining plate provided with similar inclined side wings 10 and 11 and a central attaching tongue 12 .which is secured, as by bolts as indicated at 13, to the lower ends of the Shanks 5.

Stiff tooth cultivators are usually provided with t'ront and rear sets of staggered teeth and I find it desirable to attach my shoes on the rear set of teeth, the trent set being then used to cut the soil, and the rear set with my shoesthereon, being used to separatetheweeds and leave them lying on the ground surface.

The abo-ve arrangement is shown in the present drawings, and in the following description it will be understood that each rear tooth is fitted with a shoe as now described.

The shoe comprises a substantially V- shaped bottom plate 14 forming a blade which presents forwardly converging cutting edges 15 and 16, and to the top side of the blade a V-shaped retaining plate 17 is riveted, the body of the plate being spaced from the blade to provide an interior pocket 19 which is designed to receive the tooth of the cultivating machine.

In the present instance the pocket of the shoe is adapted to receive the duck foot, as it is called, and the inserted duck toot is held against withdrawal by a pair of similar pivoted latches 18 and 18 attached to the rear edge ot the plate 17 and having hooked ends as indicated at 20 adapted to catch behind the rear ends of the wings 10 and l1. The forward edges ot the plate 14 are slightly downturned as indicated at 21.

To the rear edge ot the plate 14 I attach permanently as by riveting a plurality of shape and similarly shaped trailing Vprongs 22, the prongs being" parallel ancll"exteiidiiig approximately across the full width ot the Shee- Eeeeeeeee preeeete .e Centrally deposed hump 23 and an upturned combing and discharging end 24, and wheuvthe shoe is in use the hump operates below the ground surface and the rear extremity of the prong extends somewhat above the ground.

The'rear'edg'e :of the plate'il 'is O a \yl theprongs'fare secured to such rear edge' "The prongshaccordingly vappear in'a V-sliaped'formation lwith tlie'result that #the humps" and' the ltrailing ends 'ffthe prongs vare irregularly disposed. "A`Wlie'nf it 'is' desired to equipa stiff tooth cultivator"snch` Vas that shown with my shoes the latches are swung to the side anda shoe is""plac`ec Ripon"eaelrtooth ofthe `rear set. rhisl being done'the llatches are swungback toY catch rbehind l the` rear ends of thewings. liVhen the machine' is "in use tliew'eedsmare cut.by'the'iront'y set or row'o teetli. `and the eut'wee'ds Jare .caughtby the shoes and passed'oyer the prongs'. `r`Phe weeds and lsoil vare separated loosened being passed 'over- 'the lhumps or the prongsf'rand? the loosened earth passes 'fba'clr between Y the prongs, "wliilst"the"we`eds are caught by the uptiirnedlorlhoolred 'ends of" prongs and passed toihe Jgrounds surface where" they discharge,v on to "the soil cultivated.l

JChe teetv1 c W hen my shoes, howeverzare applied on the teer Set, ef. teet-hv the Outer eetr'ertltee 1' ends of' the adjacent slices are practically cultiyators, there being no room for any to escapeA between.

Vhilst I have shown the pocket in the shoe of a shape to receive the duck Jroot it will be readily understood that the pocket can be readily formed to receive any of the various types of teeth used on stiff tooth cultivating machines as itis `only a matter orshaping the plate 17 to accommodate the particular tooth utilized. Further it will be obvious that the shoe and the trailing teeth could be mountedl directly on carrying shanhs of their ownv and by' so doing amachinecould readily be developed and'used to advantage. Y

hat claim as my invention is:

The combination with `a ,shank and a duck tooteultiifator tooth secured'to the lower end thereof, of a weed eradicator compr-isinga substantially V-shaped Hat' lying,` plate forming a blade presenting forwardly'converging cutting edges, saidblade underlying the cultivator tooth, a retaining plate secured permanently tothe blade and ror1ning therewith an interior pocket receiving the tooth, means releasably holding the tooth within the pocket and ay plurality or similar spaced rearwardly extending prongs secured to therear egde O the V-shaped'plate, said prongs being bent vertically inf'a Zig-zag manner and 'having their rear ends inolining upwardly.
